The individual investor should differentiate the anonymity of the cryptocurrencies with the fact that transaction processes are recorded and validated using the Blockchain technology. Otherwise, the Bitcoins pass-through information would not be available. However, the process of performing this data recording requires a high computational work, as well as a lot of time.
where name1 is the current group (optional), name2 is a previously defined group, and subexpression is any valid regular expression pattern. The balancing group definition deletes the definition of name2 and stores the interval between name2 and name1 in name1. If no name2 group is defined, the match backtracks. Because deleting the last definition of name2 reveals the previous definition of name2, this construct lets you use the stack of captures for group name2 as a counter for keeping track of nested constructs such as parentheses or opening and closing brackets.

گاهی تغییراتی که قرار است در یک جریان داده شود، کم است به همین دلیل بخشی از جریان وارد دستگاه شده و بخش دیگر دستگاه را دور می‌زند. برای نمونه برای افزایش رطوبت هوا، بخشی از هوا وارد دستگاه شده و کاملاً مرطوب می‌شود سپس با بخش دیگر جریان که اصلاً وارد دستگاه نشده‌است مخلوط شده و در پایان، رطوبت هوا افزایش می‌یابد. در مهندسی شیمی، اندازه دستگاه به دبی ورودی بستگی دارد در صورتی که بخواهیم کل جریان را وارد دستگاه کنیم باید اندازه دستگاه بزرگتر شود که ممکن است از لحاظ اقتصادی مقرون به صرفه نباشد.

You should be aware of all the risks associated with foreign exchange trading and seek advice from an independent financial advisor if you have any doubts.
(?(Open)(?!))	If the Open group exists, abandon the match if an empty string can be matched, but do not advance the position of the regular expression engine in the string. This is a zero-width negative lookahead assertion. Because an empty string is always implicitly present in an input string, this match always fails. Failure of this match indicates that the angle brackets are not balanced.

In essence, Bitcoin futures represent an agreement to sell or buy a certain amount of an asset on a particular day at a price that was fixed beforehand, and to that extent, they are no different from any other derivative financial instrument of the kind, be it futures for corn, oil or soybeans. Companies and businesses buy futures to fix the price for a specific time period, which gives them the luxury of price stability even on volatile markets, while investors often use futures for hedging risks or speculations as the value of the futures contracts is based on the overall performance of an underlying asset.

There are several differences between a blockchain and a database, including the level of control. Blockchains are under a decentralized control, whereas a centralized database creates a dependent relationship between users and administrators. Users tend to prefer confidentiality, which is better achieved through a centralized database. Performance also differs, as a centralized database is able to compute information faster than blockchains.

However, Coinbase doesn’t list XRP on its exchange yet, and the addition of the cryptocurrency to custody services doesn’t guarantee that it will be offered on the exchange. But then, because Coinbase Custody is now supporting XRP, user confidence in the cryptocurrency should increase. Additionally, institutional investing in XRP will also bring more liquidity and push up volumes of the cryptocurrency, so Coinbase listing this digital asset on its exchange shouldn’t be ruled out completely.

Yes. Bitcoin has not been made illegal in any country to date, although some nations restrict its use more heavily than others. Bitcoin is often associated with crime, because it can be used to make criminal transactions. However, this is true of any currency. Bitcoin is harder for authorities to trace than digital fiat transfers, but easier to trace than cash, and most criminal transactions in the world are made with fiat, not Bitcoin.
In 2018 Coinbase launched their independant mobile wallet for iOS and Android. The wallet stores the private keys on the user’s device and only they have access to the funds. This brings Coinbase full circle as it started out as a wallet, transitioned to an exchange only (claiming that they are not a wallet) and now they are offering wallet services again.
Coinbase requires you to link a bank account, or credit or debit card to your Coinbase account to purchase cryptocurrencies. Using a bank account allows for higher limits ($100/transaction, $2,500/week), but it also takes longer to verify transactions, so you will not see money in your Coinbase wallet for two to four days (depending on your bank). And when selling Bitcoin, once the sale is confirmed, it takes two to four days for the proceeds of that sale to show up in your bank account. With a credit or debit card, limits are lower ($200/week), but you can purchase digital currencies by simply transferring funds from that bank account to the site. For these transactions, Bitcoin shows up in your Coinbase wallet instantaneously. You can also sell Bitcoin to your PayPal account, effectively cashing out, as your Bitcoin will be exchanged for local currency. This transaction, too, is instantaneous.
In April 2019, a UK corporate filing stated that Coinbase's non-U.S. revenue grew 20% to €153 million (U.S.$173 million) in 2018 resulting in a net profit of €6.6 million.[37] Coinbase UK CEO Zeeshan Feroz said the company's non-U.S. operations accounted for nearly one-third of the company's overall revenue and Reuters estimated that the company's global revenue totaled "around $520 million" in 2018.[38]

To do the mining, individual processes are carried by the users, who are responsible for recording that information in blocks, which will join the unchanging blockchain. On the other hand, as a reward, the miners will obtain for their collaboration a small number of bitcoins in the process known as Bitcoin mining. Likewise, this term also applies to the creation and distribution of Bitcoin. According to the latest Bitcoin News, the total number of Bitcoin mined is about the half of the total number of Bitcoin created during the previous year. Such diminishing number of newly mined Bitcoin means that the total number of 21 million Bitcoins in circulation will only be created by 2030.

Coinbase explains that one USDC is represented by one USD on the Ethereum blockchain.

جریان برگشتی در فرایندهایی شامل واکنش شیمیایی به علت تعادلی بودن واکنش و همچنین عدم پیشرفت ٪۱۰۰ واکنش است. در صورتی که در مواد واکنشگر جزء زائدی وجود داشته باشد که در واکنش شیمیایی شرکت نکند و جداسازی آن نیز مشکل باشد باید بخشی از جریان برگشتی به محیط دفع شود تا این جزء زائد از فرایند خارج شود. در غیر این صورت این جزء در فرایند جمع شده و باعث اشغال فضای رآکتور و فرایند می‌شود در نتیجه تولید محصول کاهش یافته و در پایان، باعث عدم تولید محصول خواهد شد.

برخی از واکنش‌های شیمیایی، تعادلی بوده و پس از مدت زمانی به رغم وجود اجزاء واکنشگر، غلظت آن‌ها ثابت بوده و در واقع واکنشگرها و محصولات با هم به تعادل می‌رسند. برای چنین واکنش‌هایی لازم است پس از انجام واکنش، محصولات، جدا شوند تا شرایط برای انجام واکنش فراهم شود. برای این منظور واکنشگرها و محصولات از رآکتور شیمیایی خارج شده و وارد بخش جداسازی می‌شوند. در واحد جداسازی، محصولات واکنش جدا شده و از فرایند، خارج خواهند شد و واکنشگرها جهت تولید محصول به رآکتور بازگشت داده می‌شوند. بنابراین یکی از دلایل وجود جریان برگشتی، تعادلی بودن و پیشرفت نکردن واکنش است. به همین دلیل است که در واکنش‌های سوختی، جریان برگشتی وجود ندارد.
